JP7164977B2 - Floor-mounted fixtures, overturn prevention devices, and base units - Google Patents

Description

TECHNICAL FIELD The present invention relates to a floor-mounted fixture, an overturn prevention device used therein, and a base unit. Furniture such as cabinets and shelves (racks) are typical examples of floor-mounted fixtures. It includes a wide range of items that are placed on the floor and may topple over during an earthquake, such as display devices for products, servers for personal computers, and distribution boards.

Many proposals have been made for means for preventing overturning of cabinets in the event of an earthquake. There are two ways to prevent overturning: one is to allow cabinets to sway while mitigating the degree of it, and the other is to prevent cabinets from moving independently even in an earthquake (because the building will move during an earthquake, the cabinets will not move). The idea is that even though the hull will sway with respect to the ground, it will not move relative to the building.)

As an example of the former method, there is a seismic isolation device for moving cabinets relative to the floor, as disclosed in Patent Document 1. On the other hand, as a means for preventing the cabinets from moving independently, as disclosed in Patent Document 2, the top surface of the cabinets is connected to the wall of the building with brackets, or as disclosed in Patent Document 3. As described above, there is a type in which a table on which cabinets are placed is provided with a forward-facing tipping prevention plate (outrigger) that protrudes in front of the cabinet. As a modification of Patent Literature 3, Patent Literature 4 discloses arranging a fall prevention plate inside the access floor.

JP 2016-2420 A Japanese Patent Application Laid-Open No. 2007-37990 Japanese Utility Model Publication No. 4-24990 Japanese Patent No. 3541362

The means of Patent Document 1 is understood to be excellent in theory, but has the problem of being significantly complicated in structure. On the other hand, the means of Patent Document 2 has a simple structure, but there is a problem that if the height of the cabinet is high, it becomes troublesome to attach brackets.

In addition, in the case of Patent Document 3, since the outriggers protrude greatly in front of the cabinet, there are problems that people are likely to trip and the aesthetic appearance is deteriorated (even if covered with carpet, the outriggers are high) Therefore, the problem has not been resolved.) If the anti-tip plate is built into the access floor as in Patent Document 4, the problem of stumbling and appearance can be resolved, but the problem is that it requires a lot of time and effort for construction, and it cannot be applied to floors other than access floors, resulting in poor versatility. There is such a problem.

The present invention was made in response to such a situation, and aims to provide a seismic damping technology which has a simple structure, is easy to construct, and has excellent practicality and versatility.

The invention of claim 8 relates to a base unit. This base unit is
"Equipped with a base on which the main fixture is placed and a fall prevention device on which the base is placed,
The fall prevention device includes a horizontal portion on which the base is placed, a first joint portion that connects the horizontal portion and the furniture, and is fixed to a wall or other furniture so that the horizontal portion does not move horizontally during an earthquake. a second junction; and

In the ninth aspect of the invention, fixtures are specified. In other words, this fixture is
"Equipped with the overturn prevention device described in any one of claims 1 to 7 or the base unit described in claim 8 "
It is configured.

It should be noted that the present invention does not exclude furniture having other functions such as shock absorbers in addition to the overturn prevention device. It is preferable to have a device that assists the overturn prevention device as an earthquake countermeasure for furniture.

When an upright piece is provided as the second joint portion in the horizontal portion, a fixed type partition is an example of a wall body as a suitable object to which this is fixed. The lower frames (baseboards, ground rails) of fixed partitions are generally made of metal and the uprights can be easily fixed using self-drilling screws such as drill screws or self-tapping screws. When fixtures such as cabinets are arranged back to back, the upright piece provided on the horizontal portion may be fixed to the rear surface of one of the fixtures. In this case, the rear surface of one horizontal portion constitutes the wall.

According to the inventions of the present application, the overturn prevention device has a simple structure made of a plate material and is easy to install. One of the features of the inventions of the present application is that the horizontal part constituting the overturn prevention device is fixed to the floor or the wall. Even if it is structured, it can prevent overturning. Therefore, it is possible to prevent the horizontal portion from being exposed to the public's eyes, degrading the appearance, and preventing people from stumbling.

As in claims 1 and 5 , when adopting a structure in which an upright piece is provided as the second joint and this upright piece is fixed to the wall, the overturn prevention device does not necessarily need to be fixed to the floor, so it is removed. It is not aesthetically pleasing afterwards and can be applied without problems to floors where anchors cannot be driven in, for example carpeted floors. Also in this aspect, it is excellent in practicality and versatility.

In addition, when the standing piece is fixed to the wall, the entire horizontal portion can bend in the vertical direction and can be deformed. As a result, it is possible to prevent an excessive load from being applied to the joint portion between the upright piece and the wall body, thereby maintaining the fixed state of the overturn prevention device and ensuring the overturn prevention effect. Therefore, as in claims 1 and 5 , it is preferable to configure the overturning prevention device with the horizontal portion and the standing piece in order to obtain a high overturning prevention effect.

As described above, the configuration of claim 7 is excellent in practicality and versatility because it is possible to prevent the horizontal portion from deteriorating the appearance and stumbling over the horizontal portion.

In the event of an earthquake, fixtures tend to sway relative to the building, so there is a possibility that a large moment will act on the fixing points of the standing pieces. Regarding this point, if the configuration of claim 2 is adopted, the kinetic energy of the fixture is absorbed by the deformation of the horizontal part while moving relative to the fixture, as described above, so that the second joint (upright piece) It is possible to suppress the moment acting on the fixed portion and improve the overturn prevention performance. The property that the horizontal portion deforms while moving relative to the furniture during an earthquake can be ensured by making the overturn prevention device made of a metal plate such as a steel plate or a stainless steel plate.

Fasteners such as screws can be used as means for connecting the horizontal part and the fixtures, but if an adhesive sheet or adhesive is used as in claim 3 , the horizontal part and the fixtures may separate or stick together. Therefore, it is possible to greatly reduce the influence of swinging of fixtures on the fixing portion of the second joint . Therefore, it is possible to prevent the overturn prevention device from being separated from the building or the like, thereby improving the overturn prevention function.

In addition, the adhesive sheet in claim 3 means that it is in a thin state in advance and is attached to the overturn prevention device, and the adhesive is applied to the horizontal part of the overturn prevention device in an atypical state. means something Moreover, the adhesive sheet includes both a single-layer structure entirely composed of an adhesive and a multi-layer structure in which adhesive layers are provided on both upper and lower surfaces of a film or sheet made of resin or the like.

In claim 4 , the grounding member such as the adjuster bolt is connected to the horizontal portion, and since the connected state can be reliably maintained by a member made of metal or the like, the durability is excellent. In addition, since assembly can be performed using screws (bolts), assembly is easy and quality stability is excellent. Furthermore, the cost can be reduced as compared with the case of using an adhesive material.

There are two types of partitions, one in which the upper end is connected to the ceiling, and the other in which the upper end does not reach the ceiling (low partition). It is The problem in this case is that the screen-type partitions are simply placed on the floor and stand by themselves, so that the partitions themselves may slip laterally in the event of an earthquake.

In this regard, if an auxiliary plate is provided as in claim 5 , the standing piece and the partition can be fixed to the floor via the auxiliary plate, so that the partition can be prevented from slipping laterally and a high overturn prevention effect can be ensured. . In addition, when the auxiliary plate is provided as in claim 5 , the horizontal portion is held on the floor through the auxiliary plate without being fixed to a wall such as a partition. Even if the fixture is not placed near the wall, it can contribute to preventing tipping over on the horizontal part.

Office floors are often double floors (access floors) with floor panels laid on top of concrete slabs. can be easily and firmly fixed with fasteners such as drill screws, tapping screws, and expandable blind anchors. A combination of a blind nut and a screw can also be adopted.

The double floor is constructed with the aim of allowing cables to be routed in the hollow space. It is pulled out on the floor from the gap. In this case, the cable may be pulled into the fixture such as a cabinet, and it is not preferable if the pull-out of the cable is blocked by the overturn prevention device.

In this respect, if the configuration of claim 6 is adopted, the cable can be pulled out inside the fixture through the window hole or the notch, so the cable can be prevented from being exposed outside the fixture and the cable can be neatly processed. can. Note that the window hole and the notch may be provided side by side. Forming a notch opening on the outer circumference has the advantage that even if a large device is connected to the cable, wiring can be performed without removing the cable from the device.

Now, for example, a horizontally long cabinet will sway in the front-back direction during an earthquake. A phenomenon of swaying in a twisted posture (horizontal turning posture) can be seen. When the cabinet is twisted in a plan view and shakes, the front corners act as if they are pushing against the floor, making it difficult for the cabinet to topple over.

Therefore, it can be said that if furniture such as a cabinet is encouraged to sway in a twisted posture in a plan view, the overturn prevention effect will be enhanced . Since it becomes easier to twist and deform, it is possible to make it easier for the furniture to swing in a twisted posture in a plan view, so it can be said that the overturn prevention effect can be improved.

Box-shaped furniture such as cabinets are often placed on a base, so if a unit is configured with a base and a fall prevention device as in claim 8 , the furniture body can be constructed in a conventional configuration. Good for versatility. It is also excellent in that it can be applied to existing furniture as it is. As in claim 9 , incorporating a tipping prevention device or a base unit into furniture can greatly improve the value of the furniture.

(1).Outline of First Embodiment Next, an embodiment of the present invention will be described with reference to the drawings. First, a first embodiment shown in FIGS. 1 to 5 will be described. This embodiment is applied to prevent overturning of the steel cabinet 1 formed in a horizontally long rectangular shape in plan view.

The cabinet 1 includes a cabinet body 2 opening forward, a horizontally rotatable double door 3 for opening and closing the opening, and a steel plate base 4 on which the cabinet body 2 is placed. The rear surface (rear surface) of the cabinet 1 is arranged overlapping (or in close contact with) the outer surface of the fixed partition 5 as an example of indoor equipment, but the depth of the cabinet 1 is much smaller than the height. , it is easy to fall forward in the event of an earthquake. Therefore, the overturn prevention device 6 is used.

The overturn prevention device (overturn prevention plate) 6 is made of steel plate and has a horizontal portion 7 positioned below the base 4 and an upright piece 8 rising from the rear edge of the horizontal portion 7. is fixed by screws 10 to a horizontal lower frame (baseboard, ground rail, runner) 9 forming the lower end of the partition 5 . A plurality of mounting holes 11 are intermittently formed in the standing piece 8 in the horizontal direction.

The partition 5 of the embodiment has a structure in which panels 13 are attached to the front and back of a frame composed of left and right vertical frames 12, a lower frame 9 and an upper frame (not shown), and the vertical frames 12 are brought into contact with the ceiling. It has a fixed structure. The lower frame 9 may be fixed to the floor, or may simply rest on the floor.

The thickness of the lower frame 9 in the front-rear direction is smaller than the thickness of the partition 5 as a whole. That is, the front and rear surfaces of the lower frame 9 are recessed inside the front and rear outer surfaces of the panel 13 in the thickness direction. Therefore, the upright piece 8 of the overturn prevention device 6 enters from the outer surface of the panel 13 to the inside. Therefore, the rear end portion of the horizontal portion 7 protrudes rearward from the front surface of the cabinet 1 .

If the overturn prevention device 6 is not attached, the lower frame 9 can be attached with left and right longitudinal cover plates. Further, when the front surface of the lower frame 9 is flush with the front surface of the panel 13, or when the standing piece 8 is fixed to the front surface of the panel 13, the horizontal portion 7 cannot protrude behind the rear surface of the cabinet 1. do not have. Furthermore, the rear surface of the base 4 may be slightly shifted toward the front from the rear surface of the cabinet body 2. In this case, even if the standing piece 8 is fixed to the panel 13, the standing piece 8 can be seen from the cabinet in a plan view. Since the rear surface of the main body 2 can be shifted forward, the rear surface of the cabinet main body 2 can be overlapped with the front surface of the panel 13. - 特許庁

The horizontal portion 7 of the overturn prevention device 6 is sized to substantially overlap the cabinet 1 in plan view, and neither the front end nor the left and right side ends protrude outside the cabinet 1 (outside the base 4) in plan view. Adhesive sheets 14 , which are an example of the first joint portion described in the claims, are attached to the left and right portions of the horizontal portion 7 . Alternatively, it is also possible that the left and right portions of the horizontal portion 7 serve as first joint portions that are connected to the base 4 via the adhesive sheet 14 . The adhesive sheet 14 is formed in a rectangular shape that is longitudinally long.

(2) Details of the base unit As shown in FIGS. 2 and 3, the basic structure of the base 4 is the same as the conventional one. Each frame 16, 17, 18 is formed in a groove shape having upper and lower horizontal pieces 19, 20 and vertical pieces 19a, 20a provided at the ends thereof.

The lower horizontal piece 20 is narrower than the upper horizontal piece 19. - 特許庁Also, the upper horizontal piece 19 of the front frame 17 is wider than the upper horizontal piece 19 of the rear frame 18, but both may have the same width.

As shown in FIGS. 2 and 3, auxiliary frames 21 that are long in the front-rear direction are arranged on the left and right sides of the base 4 . The auxiliary frame 21 is U-shaped and is open upward, and both front and rear ends thereof are fixed to the front frame 17 and the rear frame 18 by welding or the like.

As clearly shown in FIGS. 2B and 3B, the lower end of the auxiliary frame 21 is located above the lower end of the base 4, and the front and rear end portions of the auxiliary frame 21 are provided with the support elements described in the claims. As an example of the first joint portion, left and right longitudinal connecting members 22 are fixed by adjuster bolts 23 via nut plates. A receiving plate 24 is fixed to the lower surface of the connecting member 22 with bolts 25 . The connecting member 22 has a substantially M-shaped configuration when viewed from the front and has flap portions projecting on both left and right sides of the auxiliary frame 21 .

In addition, it is also possible to connect the front and rear connecting members 22 continuously. Alternatively, it is also possible to directly fix the receiving plate 24 to the auxiliary frame 21 without using the adjuster bolt 23 and the connecting member 22 . When fixing the receiving plate 24 directly to the auxiliary frame 21 , one receiving plate 24 may be fixed to one auxiliary frame 21 , or one receiving plate 24 may be fixed to two auxiliary frames 21 . may

The receiving plate 24 is separated into left and right, but it is also possible to connect them in series to form a single plate type, or to form a three-plate type with left, right, and center plates. It is also possible to fix the backing plate 24 to the lower horizontal piece 20 of the base 4 . When the adjuster bolt 23 is provided, the receiving plate 24 can also be used as a connecting member.

Although the receiving plate 24 is positioned below the base 4 in the drawing, the receiving plate 24 can be inserted inside the base 4 by increasing the height of the lower surface of the auxiliary frame 21 or the like. In this case, the appearance of the cabinet 1 is good because the gap between the base 4 and the floor can be made as small as possible.

The receiving plate 24 has substantially the same size as the adhesive sheet 14 and is set so that the entire lower surface of the receiving plate 24 overlaps with the adhesive sheet 14 . The receiving plate 24 is made of a steel plate that is thicker than the material plate of the base 4, and is rigid enough not to deform (elastic deformation and plastic deformation) even if the cabinet 1 shakes during an earthquake.

The adhesive sheet 14 only needs to have the necessary adhesive strength, and therefore, there are no particular restrictions on the composition, but it is desirable that the adhesive strength be as high as possible. Adhesion is generally defined as being peeled off when a peeling force exceeding the limit acts, and sticking again when pressure is applied even if peeled off. is possible.

(3).Summary of First Embodiment FIG. 4 shows an example of the construction procedure. First, the overturn prevention device 6 is placed at a predetermined position, and the upright piece 8 is fixed to the lower frame 9 of the partition 5 with screws 10 . A drill screw or a tapping screw can be used as the screw 10, for example. It is also possible to pre-drill tapped holes in the lower frame 9 (in this case, the mounting holes 11 for the upright pieces 8 are formed as elongated left and right long holes so that the left and right positions of the overturn prevention device 6 can be adjusted. preferably kept.).

Next, an adhesive sheet 14 is attached to a predetermined position on the horizontal portion 7 . Needless to say, release paper is attached to the front and back surfaces of the adhesive sheet 14, and the adhesive sheet 14 is attached to the upper surface of the horizontal portion 7 after peeling off one of the release papers. In order to allow the adhesive sheet 14 to be adhered to an accurate position, the horizontal portion 7 may be provided with a display line (surrounding line) or the like indicating the position to be adhered. Note that the adhesive sheet 14 can also be attached to the overturn prevention device 6 in advance.

The cabinet 1 is then placed on the horizontal part 7 . In this case, first, the base 4 is placed on the horizontal portion 7, and then the cabinet body 2 is fitted into the base 4. Alternatively, the base 4 is assembled into the cabinet body 2 in advance, and the entire cabinet 1 is placed on the horizontal portion 7. There is a method of stacking and placing them on top of each other, and either method can be adopted.

When the base 4 is arranged first, it is necessary to set the position of the base 4 accurately so that the cabinet body 2 exactly overlaps the outer surface of the partition 5 . Regarding this point, a cage having a predetermined thickness may be arranged between the base 4 and the lower frame 9 . When the height of the base 4 is higher than that of the lower frame 9, placing the base 4 with the rear surface of the base 4 in contact with the surface of the partition 5 has the advantage of accurate positioning.

The cabinet main body 2 has a bottom plate 2a, and the bottom plate 2a is provided with downward pieces 2c that enter the inside of the base 4. As shown in FIG. The cabinet body 2 may be formed by simply fitting the downward piece 2c into the base 4, or by fixing the bottom plate 2a to the base 4 with screws.

Since there is a space between the base 4 and the lower frame 9, the heads of the screws 10 do not hit the rear surface of the base 4. - 特許庁Therefore, the screw 10 can have a pot head or a hexagonal head instead of a countersunk head. Instead of fixing the screw 10 directly, it is also possible to fix a blind nut to the lower frame 9 and screw a screw into the blind nut. Alternatively, it is also possible to make a pilot hole in the lower frame 9, insert a blind anchor having an expanded portion into the pilot hole, and fasten the upright piece 8 and the lower frame 9 together with the blind anchor. is.

FIG. 5 shows the rocking movement of the cabinet 1 and the deformation of the horizontal portion 7 during an earthquake. The cabinet 1 swings back and forth due to the shaking of the floor surface, but since the rear surface hits the partition 5, it generally swings between a vertical posture and a forward leaning posture, as indicated by the dashed line and the solid line in FIG. 5(A). there is

Since the upright piece 8 of the overturn prevention device 6 is fixed to the lower frame 9 of the partition 5, when it falls forward, the horizontal portion 7 is bent upward and deformed into a mountain shape, and the rear portion of the receiving plate 24 is deformed. The adhesive sheet 14 is peeled off from the base 4 at the point 1, and when the cabinet 1 is tilted forward to some extent, the elastic restoring force of the horizontal portion 7 overcomes and the receiving plate 24 rotates back (the horizontal portion 7 is elastic). It can be transformed.).

When the cabinet 1 rotates back, it collides with the partition 5, and as shown in FIG. Backward tilting is permitted by the floating state and the angle formed by the receiving plate 24 and the upright piece 8 increasing.

For these reasons, in the present embodiment, the deformation of the overturn prevention device 6 is closely related to the shaking of the cabinet 1, and the elastic restoring force of the horizontal portion 7 after being deformed and then returning to its original state causes the shaking of the cabinet 1. It can be understood that it greatly contributes to reducing it. Further, even if the cabinet 1 and the horizontal portion 7 are partially peeled off, they are not completely peeled off and the joined state is maintained.

Therefore, it is possible to prevent the kinetic energy of the cabinet 1 from intensively acting on the standing piece 8 and also prevent the standing piece 8 from being detached from the lower frame 9 . The adhesive force of the adhesive sheet 14 is preferably as high as possible. Deformation of the horizontal portion 7 also prevents an excessive moment from acting on the fastening portion between the standing piece 8 and the lower frame 9 .

(4) Second to Sixth Embodiments FIG. 6 shows another embodiment. Among them, in the second embodiment shown in (A), the overturn prevention device 6 corresponding to one cabinet 1 is separated into left and right. Adopting such a separation method has the advantage that one type of overturn prevention device 6 can be used for furniture with different widths.

In the third embodiment shown in (B), a plurality of cabinets 1 are supported by one overturn prevention device 6, contrary to the second embodiment. In this embodiment, there is an advantage that the front surfaces of the cabinets 1 arranged side by side can be exactly aligned.

(C) In the fourth embodiment shown in (D), only the front portion of the receiving plate 24 is fixed to the horizontal portion 7 of the overturn prevention device 6 with bolts 26 and nuts 27 ((D) is the same as (C)). It is an enlarged view of the main part.). The bolt 26 has a countersunk head 26a, and the horizontal portion 7 is formed with an upward projection 28 into which the countersunk head 26a is fitted from below. is fixed with On the other hand, the receiving plate 24 is formed with a tapered recess 29 into which the upward protrusion 28 of the horizontal portion 7 is inserted.

In this embodiment as well, in the event of an earthquake, the rocking movement of the cabinet 1 and the elastic deformation of the horizontal part 7 occur simultaneously while the joint state between the horizontal part 7 and the receiving plate 24 is maintained, so that the rocking of the cabinet 1 can be suppressed. .

As shown in (E) as a sixth embodiment, it is also possible to connect the horizontal portion 7 and the receiving plate 24 via an elastic body 30 such as rubber. In this embodiment, the vibration of the cabinet 1 and the deformation of the horizontal portion 7 are allowed even if the horizontal portion 7 and the receiving plate 24 are connected at a plurality of front and rear portions. Therefore, it is excellent in stability. In addition, in the fifth and sixth embodiments, as a construction procedure, the base 4 is arranged first, and then the cabinet main body 2 is placed on the base 4 .

(5). Outline of the seventh embodiment (Figs. 7 to 12) Next, the seventh embodiment will be described. The basic aspect of this embodiment is the same as that of the first embodiment. Elements that are the same as in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted unless particularly necessary.

For example, as shown in FIG. 12, nut cylinders 32 are fixed to both front and rear ends of the auxiliary frame 21, and an adjuster bolt 23 for height adjustment, which is an example of a grounding body, is screwed into the nut cylinders 32 from below.

As clearly shown in FIG. 9, steel plate fixing metal fittings 33 are fixed by welding to the four corner portions of the horizontal portion 7 of the overturn prevention device as components of the first joint portion. As shown in 12, an inverted M-shaped connecting member 22 is fixed to a fixing metal fitting 33 with a bolt 34 (see FIG. 12). Therefore, the fixing metal fitting 33 has a tapped hole 35 for fixing the connecting member 22, as shown in FIG. 9A, for example.

A protrusion 33a is formed on the front fixing metal fitting 33 to face forward, and a rearward protrusion 33a is formed on the fixing metal fitting 33 on the rear side. The protrusion 33a is provided for stably mounting the adjuster bolt 23 thereon. That is, in order to stably support the cabinet 1, it is preferable to arrange the adjuster bolts 23 as close to the periphery of the base 4 as possible. As a result, the horizontal portion 7 may become difficult to deform. Therefore, the projecting portion 33a is provided in order to stably support the adjuster bolt 23 while minimizing the area of the fixture 33 as much as possible.

A pair of front and rear tapped holes 35 are provided in the fixing bracket 33 in order to match the type of the wall body such as the partition 5. As shown in FIG. That is, as shown in FIG. 8, when applying to the partition 5 provided with the lower frame 9 recessed from the wall surface, the connection plate 22 is fixed using the front tapped hole 35, and the connection plate 22 is fixed as shown in FIGS. Thus, when the upright piece 8 is fixed to the wall surface of the partition 5 or the like, the connection plate 22 is fixed to the rear tapped hole 35 . Therefore, one type of overturn prevention device can be used for both partitions with lower frames and partitions without lower frames.

Further, the adjuster bolt 23 is inserted through the upward bulging portion of the connecting member 22 from below. From a different point of view, the connecting member 22 is formed with an upwardly protruding portion in order to form an arrangement space for the head of the adjuster bolt 23 . The base 4 is inseparably connected to the horizontal portion 7 via a connecting member 22 and an adjuster bolt 23, and the height of the base 4 can be adjusted by rotating the adjuster bolt 23. As shown in FIG.

A spring washer or rubber ring overlapping the bearing surface of the adjuster bolt 23 is fitted to prevent the head of the adjuster bolt 23 from rattling between the fixing metal fitting 33 and the connecting member 22 during an earthquake. It is also possible to keep .

In this embodiment, the horizontal portion 7 is formed with a cutout portion 36 that opens forward. Although the cut-open portion 36 is formed in the left-right middle portion, it is also possible to form it in a plurality of left-right portions. The depth (depth) of the cut-out portion 36 is about 1/3 of the depth dimension of the horizontal portion 7, but the left-right width and depth can be set arbitrarily. It is also possible to form it in a rearwardly open state.

By forming the cutout 36, the cable pulled out from the inside of the double floor can be pulled out to the inside of the cabinet 1 without being exposed to the outside. Further, since the horizontal portion 7 is easily torsionally deformed, there is an advantage that the damage of the horizontal portion 7 can be prevented. As shown in FIG. 9A, the cables can be pulled out by providing a circular window hole 38 instead of or in addition to the cutout portion 36 . It is also possible to form a plurality of cut-open portions 37 on the left and right.

In this embodiment, as shown in FIG. 7, a shock absorber 41 having an elastic body 40 fixed to the rear surface of an L-shaped plate 39 overlapping the upper and rear surfaces of the cabinet body 2 is used. The elastic body 40 is made of a material having appropriate elasticity such as synthetic resin or elastomer, is formed in a U shape with a forward opening, and is fixed to the rear surface of the L-shaped plate 39 . The buffer 41 has a kind of hollow structure.

In the event of an earthquake, the cabinet 1 may rotate back and collide violently with the partition 5, but if the buffer 41 is provided as in the embodiment, the partition 5 can be prevented from being damaged or deformed. In addition, since the upper end of the cabinet body 2 is supported by the partition 5 via the buffer 41, it is possible to prevent the cabinet 1 from vibrating due to retraction of the drawer or the like.

Furthermore, the upper end of the partition 5 is fixed or locked to the ceiling surface via a ceiling rail or the like. However, if the shock absorbers 41 are provided as in this embodiment, even if the cabinet body 1 rotates backward and hits the partition 5 in the event of an earthquake, the impact can be alleviated. can also be prevented.

The action during an earthquake is the same as in the first embodiment, and even if the cabinet 1 shakes back and forth, the overturn prevention device 6 can prevent it from falling over. In this case, the horizontal portion 7 of the overturn prevention device 6 is deformed as shown in FIG. 5A to allow the cabinet 1 to swing. 7 is in a state in which deformation is easy. As a result, it is possible to reduce the elastic restoring force generated in the horizontal portion 7 and prevent the cabinet body 2 from violently colliding with the partition 5 due to the return rotation.

Now, when observing the shaking of the cabinet 1 in the earthquake reproduction experiment, for reasons such as the position of the center of gravity being shifted left and right or front and back from the center, as shown in FIG. A phenomenon of rocking back and forth while twisting in a (horizontal rotation) posture can be seen. In such a twisted posture, the front corner portion 2a of the cabinet 1 protrudes forward from the normal position (more precisely, the front adjuster bolt 23 shifts forward from the normal position), causing the cabinet 1 to overturn. difficult to do.

When the notch portion 36 is formed as in the seventh embodiment, the horizontal portion 7 of the overturn prevention device 6 is also likely to be torsionally deformed, and the cabinet 1 is likely to be in a twisted posture in plan view, thereby preventing overturning. It can be said that the effect can be improved.

(6).Eighth embodiment (Figs. 13 and 14)
In the eighth embodiment shown in FIGS. 13 and 14, the cabinet 1 is fixed to the partition 5 of the screen type. That is, the cabinet 1 is arranged along the front surface of the screen-type partition 5 . The partition 5 has a hollow lower frame 43, and an adjuster bolt 44 is screwed into the lower frame 43 from below.

On the other hand, the rear portion of the overturn prevention device 6 is provided with a rear auxiliary plate 45 fixed to the floor surface with a screw 46, and a rear wall plate 45a is formed by bending the rear end of the rear auxiliary plate 45. The wall plate 45a and the upright piece 8 of the overturn prevention device 6 are fastened together to the rear frame 43 of the partition 5 with screws 10. As shown in FIG.

If the partition 5 is of the screen type, the partition slides laterally or moves up and down during an earthquake, and the fixing function to the cabinet 1 cannot be expected. When the rear wall plate 45a and the upright piece 8 of the overturn prevention device 6 are fastened together to the partition 5, the upright piece 4 is fixed to the floor F via the auxiliary plate 45, and the partition 5 serves as a reinforcing plate for the rear wall plate 45a. , the effect of preventing the cabinet 1 from overturning can be ensured.

In this embodiment, the rear wall plate 45a of the auxiliary plate 45 also constitutes the wall described in the claims. Therefore, the wall is composed of the partition 5 and the rear wall plate 45a. Further, the auxiliary plate 45 is also an example of the second joint described in the claims. Therefore, it can also be considered that the overturn prevention device 6 is composed of the main plate provided with the standing piece 8 and the auxiliary plate 45 provided with the rear wall plate 45a.

If the partition 5 is not arranged, it is also possible to use only the auxiliary plate 45 to prevent overturning. When the cabinet 1 is arranged like islands on the floor without the partition 5, the rear wall plate 45a of the auxiliary plate 45 is exposed to the outside. A cover may be provided to cover 45a from the outside.

Since the rear auxiliary plate 45 is arranged only in the rear portion, the horizontal portion 7 of the overturn prevention device 6 is uneven. Regarding this point, as indicated by the dashed line in FIG. 13B, an adjustment plate 45' having the same thickness as the auxiliary plate 45 is fixed to the lower surface of the portion of the horizontal portion 7 where the fixing metal fitting 33 is positioned. I should put it on. However, while the thickness of the auxiliary plate 45 is small, the horizontal portion 7 has a certain amount of front-to-rear width. The height difference between the front and rear can be adjusted with the adjuster bolt 23.).

Although the floor panel 47 is depicted as a simple flat plate, it actually has feet that rest on a concrete slab. In addition, the periphery is bent downward to increase the rigidity. Although the floor panel 47 of the embodiment is made of steel, it can also be made of concrete or synthetic resin. The auxiliary plate 45 can be fixed to the steel floor panel 47 with tapping screws or drill screws. The above-mentioned blind anchor may be used for fixation, and in this case, a much higher fastening strength can be obtained than when a screw-in fastener is used.

(7) Ninth and tenth embodiments (Fig. 15)
In the ninth embodiment shown in FIG. 15A, two cabinets 1 are arranged back-to-back, and a fall prevention device 6 having a standing piece 8 is connected to the bases 4 of both cabinets. Then, the rear portions of the two overturn prevention devices 6 are attached to the wall plate 45a erected from the auxiliary plate 45 inserted below the two bases 4, in the same manner as shown in FIG. 49 are tightened together.

Therefore, in this embodiment, the auxiliary plate 45 is an inverted T shape having wall plates 45a in the front and rear intermediate portions, and only the wall plates 45a function as the walls described in the claims. Auxiliary plates 45 are fixed to the floor surface F with screws 46 below the two cabinets 1 in the same manner as shown in FIGS. In this embodiment, since the two cabinets 1 are connected via the auxiliary plate 45, the stability of the cabinet 1 can be significantly improved. If the upper ends of the cabinets 1 adjacent to each other in the front and rear direction are connected with a joint member (not shown), the overturning prevention effect is greatly improved.

Instead of using the inverted T-shaped auxiliary body 45, two of the L-shaped auxiliary plates 45 used in FIG. may be integrated by fixing with ).

In the tenth embodiment shown in FIG. 15(B), the cabinets 1 are arranged independently in an island shape, and the overturn prevention device 6 is provided with standing pieces 8 in front and behind the horizontal portion 7. there is Therefore, the overturn prevention device has a U-shape with an upward opening when viewed from the side. In this embodiment, auxiliary plates 45 are arranged below the front and rear portions of the overturn prevention device 6 , and wall plates 45 are provided on the front and rear auxiliary plates 45 . The wall plate 45 b of the auxiliary plate 45 and the upright piece 8 of the overturn prevention device 6 are fixed with screws 48 and nuts 49 .

In this embodiment, since the cabinets 1 are arranged independently like islands, they oscillate in the front-rear direction with the reference attitude as a boundary in the event of an earthquake. Therefore, the horizontal portion 7 of the overturn prevention device 6 is deformed in such a manner that the curved state shown in FIG.

In this way, the anti-rolling device having the standing pieces 8 provided at the two front and rear portions of the horizontal portion 7 is arranged back-to-back so that the standing pieces overlap each other in the front-to-rear direction. The standing pieces may be connected to each other with fasteners such as screws. With this configuration, the cabinets restrain each other against overturning, so that a high anti-rolling effect can be exhibited without a wall member such as a partition.

The auxiliary plate 45 is fixed to the floor F with screws 46, but as shown in FIG. there is In this embodiment, the cabinet 1 can be prevented from falling forward or backward. Therefore, even if the cabinets 1 are arranged independently like islands, a high overturn prevention effect is exhibited. In addition, it is also possible to connect the front and rear auxiliary plates 45 in a series to form a single auxiliary plate.

(8) Eleventh to thirteenth embodiments (Fig. 16)
The eleventh embodiment shown in FIG. 16 is a modification of the embodiment of FIG. 15(B). That is, in this embodiment, when the wall plates 45 a are provided on both front and rear ends of the auxiliary plate 45 , the front and rear wall plates 45 a are provided integrally with the standing piece 8 . In other words, one metal plate (steel plate) is used to form the auxiliary plate 45 so as to be integrally continuous with the overturn prevention device 6 . In this embodiment, the process of fixing the upright piece 8 and the wall member 45a is not necessary, so construction is easy.

The twelfth embodiment shown in FIG. 16B is a modification of the eleventh embodiment. That is, in this embodiment, when the upright piece 8 of the overturn prevention device 6 and the wall plate 45a of the auxiliary plate 45 are integrally connected, the upper part is formed as the overlapped portion 51 that overlaps exactly. There is a space between them at the lower part. Therefore, the horizontal portion 7 of the overturn prevention device 6 is easily deformed. The overlapped portion 51 may be simply folded, or may be fixed by spot welding.

The thirteenth embodiment shown in FIG. 16(C) uses blind anchors 51 as fixing means. In this embodiment, the blind anchor 51 is used to fix the upright piece 8 of the overturn prevention device 6 to the rear frame 9 of the partition 5 . This blind anchor 51 is widely known and has a cylindrical body 53 having a flange head 52 and a screw 54 screwed into the cylindrical body 53. By screwing the screw 54, the blind anchor 51 is formed into the cylindrical body 53. The expanded portion 55 thus expanded is expanded and deformed inside the rear frame 9 .

As described above, when the expandable blind anchor 55 is used as a means for fastening members together, even thin plates can be fastened together with a significantly high strength, so it can be said that a high overturn prevention effect is exhibited. In addition, as mentioned above, it is also excellent in that it can be fixed with high strength to a concrete floor panel.

(9).14th to 19th embodiments (Figs. 17 to 19)
The fourteenth embodiment shown in FIG. 17 has the cabinet 1 fixed to the LGS wall 58 . That is, the LGS wall 58 is composed of an upwardly-opening U-shaped runner 59 fixed to the floor F with a screw or the like, a group of a large number of light-gauge steels 60 supported inside the runner 59, and light-gauge steel 60. It is provided with a panel 61 such as a gypsum board stretched on a frame, and is often used as a partition between rooms. Although the lightweight section steel 60 is shown as a hollow square in the drawing, a channel material having a C-shaped cross section is also frequently used.

The upright piece 8 of the overturn prevention device 6 penetrates the panel 61 and is screwed into the runner 59 . Since the LGS wall 58 is lightweight and has low strength, using the auxiliary plate 45 together as in the embodiment of FIG.

FIG. 17 shows a state in which the LGS wall 58 is erected on the floor surface F. In the case of a double floor, runners 59 are fixed to the floor slab G as shown in FIG. 18(C). and hidden under the floor panel 47. Therefore, when the cabinet 1 is placed on a double floor, the upright piece 8 of the overturn prevention device 6 is placed through the panel 61 by a stud. It should be fixed at 60.

In this case, since the arrangement pitch of the studs 60 is quite large, fastening with only one screw may cause an excessive load to be applied to the single screw during an earthquake, causing the screw to slip out of the stud 60. There is Therefore, in the fifteenth embodiment shown in FIG. 18, the upright piece 8 is fixed to the stud 60 with a plurality of screws. The upper and lower sides of 11b are formed in a large number of upper and lower two stages (multiple stages).

That is, the left and right pitches of the mounting holes 11a and 11b are set so that at least three upper and lower mounting holes 11a and 11b overlap within the width of the stat 60, and the upper mounting hole group and the lower mounting hole group The groups of 11a and 11b are arranged in a zigzag arrangement so as to shift in the left-right direction. With such a configuration, the standing piece 7 can be fixed with a plurality of screws regardless of where the stud 60 is positioned.

In the embodiment, the six mounting holes 11a and 11b overlap the vertical frame 60, but according to experiments conducted by the inventors of the present application, the required fastening strength could be secured by fixing with three screws. The locations where the screws are placed are blacked out, but they may be fixed at multiple other locations.

In the embodiment, in the mounting holes 11a and 11b in the lower stage, a perfectly circular mounting hole 11a and a laterally elongated mounting hole 11b are formed. When fixing to the lower frame 9 of the partition, the upright pieces 7 can be fixed to the lower frame 9 at a predetermined pitch by using the elongate mounting holes 11b. In addition, if the mounting hole 11b is formed as an elongated hole, the overturn prevention device can be shifted in the left-right direction. Positioning of the overturn prevention device 6 can be accurately and easily performed by adopting a procedure of setting the right and left positions accurately, then fully tightening, and then driving screws into other mounting holes.

This anti-overturn device 6 can also be used for the partition 5 in which the lower frame 9 is set inside the surface of the panel 13 as shown in FIG. Since the lower frame 9 is strong, if the cabinet 1 has a width of 900 mm, the necessary strength can be ensured with a total of about six screws, three on each side. Therefore, the mounting holes 11b of the elongated holes are formed at a pitch P of 100 mm from the middle of the left and right sides to the left and right sides. That is, as described above, the elongate mounting holes 11b are formed at a predetermined pitch P as a guideline for selecting the position when fixing to the lower frame 9. As shown in FIG. It should be noted that the number of screws to be used for fastening should be determined on site, taking into account the plate thickness of the lower frame.

As already explained with reference to FIG. 19(A), during an earthquake, a phenomenon is observed in which the cabinet 1 rocks back and forth in a twisted posture (horizontally rotated posture) in plan view. The phenomenon can promote the fall prevention effect.

Therefore, in the sixteenth embodiment shown in FIG. 19B, by forming ribs 62 in the horizontal portion 7 of the overturn prevention device 6 in an inclined posture, the horizontal portion 7 follows the twist of the cabinet 1 and is easily deformed. Consideration is given to A slit may be formed instead of the rib 62 . In addition, a notch 36 that is open rearward is formed in the left-right middle portion of the horizontal portion 7 .

In the seventeenth embodiment shown in FIG. 19(C), in the structure in which the upright piece 8 at the rear of the overturn prevention device 6 is fixed to the lower frame 9 of the partition 5, the upright piece 8 is provided with an auxiliary plate 45 having a wall plate 45a. The front end of the horizontal portion 7 is also bent to form an auxiliary plate 45 that rides on the floor surface F. As shown in FIG.

The front and rear auxiliary plates 45 are fixed to the floor panel 47 by blind anchors 55 (the horizontal portion 7 is formed with relief holes for allowing the blind anchors 55 to be inserted). The upright piece 8 and the wall plate 45 a are also fastened together to the lower frame 9 with blind anchors 55 .

In this embodiment, the upright piece 8 has a double structure, and the front and rear auxiliary plates 45 are fixed to the floor panel 47, thereby exhibiting an extremely high overturn prevention effect. I get it. Also in this case, it is possible to form a notch portion 36 in the horizontal portion 7 as shown in FIG. The auxiliary plate 45 does not necessarily have to be formed over the entire length of the horizontal portion 7 in the left and right direction. For example, the arrangement mode can be arbitrarily set, such as forming only at two locations on the left and right, only at the intermediate portion on the left and right, or at three locations on both sides of the intermediate portion on the left and right.

Further, instead of forming the auxiliary plate 45 by bending the horizontal portion 7, it is also possible to manufacture the auxiliary plate 45 as a separate member and fix it by spot welding. This point is the same for other embodiments provided with the auxiliary plate 45 .

In FIG. 20, the overturn prevention device 6 does not have a standing piece, and the horizontal portion 7 is fixed only to the floor F. In FIG. First, in the 18th embodiment shown in (A), a plurality of fastening holes 64 are provided in a portion sandwiched between the left and right fixing metal fittings 33 in the horizontal portion 7, and a fixing hole 64 is fixed outside the area in which the fastening holes 64 are provided. A cut line 63 is formed in order to allow the portion where the metal fitting 33 is provided to deform so as to move upward.

Therefore, in this embodiment, the overturn prevention device is a rectangular steel plate, and the fastening hole 64 is the second joint. The form of the cut line 63 can be set arbitrarily. It is also possible to form slits instead of the cut lines 63 . As the fastening means, it is preferable to use expandable blind anchors or blind nuts.

In the 19th embodiment shown in FIG. 20(B), an auxiliary plate 45 is integrally connected to the rear end of the horizontal portion 7, and the auxiliary plate 63 is fastened with a fastener such as a screw or an expandable blind anchor. It's becoming In this embodiment, the rear half of the auxiliary plate 45 is also deformed during an earthquake.

In the twentieth embodiment shown in FIG. 20(C), the auxiliary plate 45 is formed of a member separate from the horizontal portion 7, and the horizontal portion 7 is fixed to the auxiliary plate 45 by spot welding 65 at the front and rear intermediate portions. there is Further, the auxiliary plate 45 is fixed to the floor F with an anchor.

In these examples (A) to (C), the horizontal portion 7 is fixed to the floor F, so even if for some reason it cannot be fixed to a wall such as a partition, the furniture can be prevented from falling over. Moreover, it is also suitable for arranging fixtures in an island shape. In the example of FIG. 20(C), the horizontal portion 7 is designed to bend symmetrically in the front-rear direction, so it is suitable for fixtures arranged like islands.

In the twenty-first embodiment shown in FIG. 20(D), the horizontal portion 7 of the overturn prevention device 6 is pressed and held on the floor via an elastic cylinder 66 . Therefore, the horizontal portion 7 can be floated or deformed by deforming the elastic tube 66 . Therefore, it is possible to allow the furniture to move and prevent it from overturning. Since a large load is applied to the fastening point of the horizontal part 7 of the floor, in this embodiment, an expandable blind anchor 55 is used as a fastener.

(10). Others Although the embodiments of the present invention have been described above with reference to the drawings, the present invention can be embodied in various other ways. For example, the target fixtures are not limited to cabinets, and as mentioned in the technical field section, electrical and electronic equipment, vending machines, refrigerators, product display shelves, etc. are also targets. Moreover, when fixing to a wall, it is possible to fix to a concrete wall, and it is also possible to divert the back plate of the fixtures placed back to back as the wall.

The grounding part of the fixture does not necessarily have to be an adjuster bolt. It may be a downward protrusion that does not have a height adjusting function. Alternatively, the lower surface of the base can be overlaid on the horizontal portion over a large area (solid overlaid).

INDUSTRIAL APPLICABILITY The present invention can be embodied in an overturn prevention device for furniture. Therefore, it can be used industrially.
